public class QueryPerTableRowCounter
extends Object
implements RowCounter

RowCounter that issues one SELECT COUNT(*) per table, by looping IDatabaseConnection.getRowCount(String). Already handles schema qualification and DatabaseConfig.PROPERTY_ESCAPE_PATTERN through QualifiedTableName, and is exercised across every supported database by that method's own tests.

This is the RowCountCheck v1 implementation, and the value DatabaseConfig.PROPERTY_ROW_COUNTER initialises to.
